Thanks Romain for this review (and for bringing me in!)

However, I disagree: these defconfig files are for qemu, not the real
hardware.

Additionally, we do have a configuration for the hifive unleashed board
already, hifive_unleashed_defconfig, which is what should be used for
the real hardware.

Yann E. MORIN.
